Sequentially, the last stage to occur among the following is:
Options
- ADiakinesis
- BPachytene
- CZygotene
- DLeptotene
Correct answer
A. Diakinesis
Step-by-step solution
The meotic Prophase I consists of five stages namely - Leptotene, Zygotene, Pachytene, Diplotene and Diakinesis. During the leptotene stage the compaction of chromosomes continues and they become more visible under light microscope. In second stage chromosomes start pairing together to form homologous chromosomes through the process of synapsis. During pachytene these bilvalent chromosomes now appear as tetrads and recombination nodules also appear. During the start of diplotene phase there is dissolution of synapt
